Adults: Refer to the specific product information or guidelines for adult dosage, as it may vary based on the indication and formulation used.

Mechanism of action

Dextran acts as an osmotic agent. When administered intravenously, it increases plasma volume by drawing water into the vascular space. This expansion of blood volume helps in maintaining blood pressure and improving perfusion to tissues.

Pharmacodynamics

The pharmacodynamics of dextran involves its ability to enhance blood flow and reduce blood viscosity. It can improve rheological properties of blood, thereby facilitating better circulation. Dextran's molecular size allows it to remain in the circulation for an extended period, contributing to its volume-expanding effects.

Pharmacokinetics

Dextran is administered intravenously and is distributed in the vascular compartment. Its elimination occurs through renal filtration, and it is eventually degraded by enzymatic action in the liver. The half-life can vary depending on the molecular weight of the dextran used, with larger molecules generally having a longer half-life.

Contra-indications

• Hypersensitivity to dextran or any component of the formulation
• Severe renal impairment
• Congestive heart failure
• Active bleeding or hemorrhagic disorders

Adverse effects

• Allergic reactions, including anaphylaxis
• Fluid overload
• Hypotension
• Headache
• Nausea and vomiting
• Fever
• Thrombocytopenia
• Acute kidney injury

Interactions

• Anticoagulants - may enhance the effects of anticoagulants leading to increased bleeding risk
• Diuretics - may increase the risk of fluid overload and electrolyte imbalances

Precautions

• Use with caution in patients with cardiovascular disease
• Monitor fluid balance closely in patients with renal impairment
• Careful administration in patients with a history of allergic reactions

Pregnancy

Safety during pregnancy has not been established. Use only if clearly needed and potential benefits justify potential risks.

Breast-feeding

Excretion in human milk is unknown. Caution is advised when administering to nursing mothers.

Storage

Store at room temperature, away from direct sunlight and moisture. Do not freeze.

Formulations

• Injectable solution for intravenous infusion
• Oral formulations (less common, specific to certain indications)
